Outboard pursuit

[Outboard]

Hey guys/girls

I have started building a FE O.S powered Pursuit boat.
You can imagine i will be left with quite a bit of space inside the hull.

What is everyone thoughts on mounting 2 battery packs down the centre of the hull instead of side by side/ conventional way?

I thought better centre of gravity= better handling and less chance of flips etc

thanks

I think mounting them as low as possible should take priority over how wide the weight is disperced. From a physics standpoint, wider mounting should be more resistant to change, in this case rocking or chine walk, but tgat may potentially hurt maneuverability. Being realistic, the numbers are too small to actually matter.

Lots of good information:

Just thought about having them together standing up another option?

If it does'nt throw your cog off down the center is better.

How did you decide to mount the OB? Is the prop center line above the keel or????

I have the parts to do this, I just want to make sure I mount it in the right place the first time.

The prop shaft is in centre of the keel, with adjustment either way. Ill take come picture if you like.

[ray schrauwen]

I understand. The pictures you already posted show it pretty well. Just needed to be sure.

I am just at the point of starting to mount down the esc, battery trays and routing the wires as neatly as possble

Very nice.

Very nice.

Thanks Beaux, its my first boat build

I need some help deciding on how to go about mounting the batteries. Should i place them flat away from each other like this

Or should i have them sitting against each other standing upright, this way will only require one battery mount and looks neater. I'm more worried how the hull will respond to either setup? Any help would be greatly appreciated

Standing upright should be fine, and it does look neater.

Just be sure you have room to move them as far back as possible to adjust your center of gravity, should be approx. 30 %.

The way they are positioned now is at 30, those two marks in the last photo on the masking tape indicate 30% and 27%.
I'll bite the bullet and mount them this way, I just hope the hull doesn't want to roll over

What size motor are you running. That boat looks good with an outboard.That's a good esc I'm running one in my DF Pirate.
